Latest Jet Results from Tevatron
s = 1.96 TeV from the CDF and DØ experiments. The jet inclusive cross section, measured using both the Midpoint and the KT jet clustering algorithm, is compared to next-to-leading order QCD prediction in different rapidity regions. The b-jet inclusive cross section measured exploiting the long lifetime and large mass of B hadrons is presented and compared to QCD prediction. A complementary meas...
متن کاملLatest Jet Results from the Tevatron
The production of particle jets with high transverse momenta in hadronic collisions is described in perturbative Quantum Chromodynamics (pQCD) as resulting from the hard scattering of strongly interacting constituents of the colliding hadrons. Inclusive jet rates observed in hadronic collisions at high values of transverse momenta provide a basic test of pQCD. The DØ and CDF collaborations1,2 h...
متن کاملLatest Results from Na60
The NA60 experiment has measured the production of muon pairs and of charged particles in In+In collisions at a beam energy of 158 A GeV. For invariant dimuon masses below the φ the space-time averaged ρ spectral function was isolated by a novel procedure. It shows a strong broadening but essentially no shift in mass. The production of J/ψ was measured as a function of the collision centrality....
متن کاملLatest Results from HERA
Deep inelastic scattering of leptons off nucleons has played a fundamental role in the understanding of the structure of the nucleon. At the HERA electron proton collider it is possible to study the proton in new kinematic regimes, in particular at low Bjorken-x and at large virtualityQ2. Due to the large centre of mass energy of 300 GeV HERA is also an important facility to search for new phen...
متن کاملLatest Results from K2k A
The possible existence of neutrino masses is the first signal beyond the standard model, which suggests grand unification. The KEK-to-Kamioka long-baseline neutrino experiment (K2K) 1 is motivated by the atmospheric neutrino anomaly found by the Kamiokande experiment . One possible explanation of the anomaly is neutrino oscillation. Later, the Super–Kamiokande (SK) group confirmed the deficit o...
